What it does :
Bentonite is used to clarify and chillproof beer. It is also used in winemaking.
What it is:
This is a non-organic material combined with a form of powdered clay.
How it works:
Bentonite causes colloidal material such as phenols, haze-causing proteins, and tannins, to drop out of solution in the beer before bottling or kegging.
This clay-like material electrostatically attracts proteins and color-altering tannin complexes from the beer via adsorption and coagulation.
Add 4 teaspoons per 5 gallons. Add to secondary fermentation 1 week before bottling.
Use of Bentonite produces a lot of sediment.
Dissolve 4 teaspoons in 0.5 cup of boiled water, cool, add to the fermenter, and mix thoroughly.
